I'm a monster in Demon King's Castle

Li Yue used photic pigments to unfold a list in mid-air, recording the types of curses currently available for selection in the colosseum.

It was like a virtual interface.

Of course, this wasn't a visualization effect provided by the Twin Swords insignia; it was just Li Yue using the method he was most familiar with to materialize everything he perceived from the authority, in order to help Yingying understand better.

In the flickering candlelight, the flames thrived.

After handling the Killing Desire of 3 Qualities, the authority of the colosseum was nourished, and when it burned, it was finally no longer so weak and morbid.

Among the curses given by the authority, the one Li Yue was most familiar with was, of course, the "Opposition" originally used by Oogie Boogie, which was also the reason why foreign adventurers needed blurry glasses to venture into the colosseum.

Through eye contact and locking on, the effect was an endless battle.

In the past, countless adventurers and demons had died under this curse, but now it was under Li Yue's control.

Apart from Opposition, there were also curses such as Separation, Weakness, Plague, Gigantification, Disarm, and Silence on the interface.

Separation would cause the beings within the cursed area to inexplicably disintegrate, including the gladiators' bodies, the weapons in their hands, and even their thoughts...

Could it be that the Demon King mentor... foresaw at this time that he might possess the dual authority of the Library and the Colosseum?

"You can use the Killing Desire to intricately use curses, and also set up permanent curses like Oogie Boogie..." Aka said while communicating with Li Yue and the candlelight.

Ling Xin's cerebral sulcus tightened.

"Tsk, everyone starts as a dog, what's he being so superior about..." Aka twitched his cerebral sulcus, taking it for granted.

"Does it work on everyone? That's like the Gambling Demon." Yingying commented after looking at the effects of several curses.

【Moreover, the colosseum is born for Killing Desire, so it's reasonable to have some combat-related curses, but the Library...】

Although Ling Xin noticed the subtle exchange between Aka and Yingying, he didn't interrupt it this time, and didn't even react at all.

Aka, of course, also thought of the Library's curses, thinking of those inexplicable knowledge.

"Perhaps only when the colosseum climbs back to the 'pillar' can I use the curses freely..."

Very convenient.

"Only dogs are afraid." Twin Swords chuckled, "You can try it."

But if the opponent was a mage like Sharrash or Vinnie, Silence would undoubtedly be Oogie Boogie's sharpest weapon.

【What about this Library?】

After deepening his understanding with Twin Swords, Ling Xin knew that this Demon King-level vampire was just foul-mouthed, but he was still very cooperative with himself and quite polite to the Library's demons.

Moreover, curses like Separation and Plague were obviously developed by Oogie Boogie himself.

【What?】

Aka shook his head.

Plague was the same; being cursed would result in constant infection, which was also suitable for Oogie Boogie to use, but the effect of Plague wasn't immediate, and Oogie Boogie didn't choose it in the final ritual under his ultimate consciousness.

Otherwise, Aka might be growing a brain tumor right now.

"Curses come from authority; I can only develop curses that are more suitable for my own combat..." Aka sensed Li Yue's insignia and the candlelight, explaining Yingying's doubts.

"So, which one do we choose?" Yingying brought up the realistic topic, helping Aka focus.

Yingying noticed this unnatural pause.

【Don't overthink it; focus on what's in front of you.】

Yingying asked about the Library's curses.

Moreover, Aka suspected that even if the colosseum's curses couldn't affect Twin Swords now, as long as the authority's status continued to rise, there would eventually be a way to take down the Demon King level.

If Disarm was added, wouldn't that mean even the attack method of throwing garbage couldn't be done?

This was clearly a curse tailored for Oogie Boogie—he himself was composed of countless Gluttonous Flies, unafraid of fragmentation, which was why he chose the two curses of Opposition and Separation in the final ritual, forming Twin Swords.

"Dog's things only work on dogs, right?" Twin Swords grasped Aka's thoughts.

Gigantification could amplify everything about the gladiator, suitable for inciting larger-scale battles and triggering more Killing Desire; Disarm and Silence were relatively easier to understand, roughly equivalent to certain conditions of battle.

【Ling Xin is Demon King level; the colosseum can barely be called a small pillar now, so it can't affect him.】

Not really; Ling Xin could develop the curses most beneficial to himself by deepening his control over the authority.

"Opposition, Separation, Plague, Weakness... these are basically beneficial to Oogie Boogie, and it's the limit of what I can do." Aka pondered, finding that only a curse like "Silence" might have the least impact on Oogie Boogie.

"But using and changing curses requires consuming a lot of Killing Desire... the cost is very high..."

【These curses originated from Oogie Boogie; he controlled them through the status of the pillar, so even if the authority declines, some are still retained...】

If curses were used well, they could have the effect of turning the tide of battle.

Oogie Boogie never played fair games, but the targets of the curses weren't differentiated, which was clearly not his style.

These were all curses often used by Oogie Boogie.

But in reality, Aka had also tried to directly apply the curse to Twin Swords himself, but it was completely ineffective.

Aka telepathically communicated with Yingying.

The more Ling Xin thought about it, the more mysterious it became, and the more afraid he became, his whole brain shrinking into a ball.

Health, as the name suggests, is the enhancement of the body within the area, with physical strength, energy, and magic power constantly flowing.

Aka diverged from the purpose of the facility, imagining the reasons for the curses, and suddenly his cerebral sulcus twitched.

【Extraction, Completion, Concealment... could these originally be the curses of the Library?】

If the Library was born for the inheritance of knowledge, then "Extraction," "Completion," and "Concealment" obviously fit this characteristic very well.

While Loathsome, Noteworthy, and Rebellious... are very suitable for the colosseum?

Aka became agitated.

In Aka's understanding, this was also beneficial to Oogie Boogie himself—Health relied on recovery ability, and the flies within the bag demon's body constantly reproduced, so when the Health curse took effect, it would undoubtedly provide him with an advantage.

Just now, Aka had used "Opposition" as a small test, stimulating the opposition of the red-skinned demon souls within Ling Xin's cloak.

"I tried it; did you forget?" Aka pointed to Twin Swords' red cloak.

Thinking closely, taking Aka as an example, Soul Impact, Withering Thorns, Undead Aria, Petrification Ray—these are all magic, and if silenced, he could only use physical-type Bone Sea and Wolf Fang, the impact would actually be small.

Yingying forcibly occupied Aka's head, smoothing out the cerebral sulcus, dragging his thoughts back to reality.

【It's not the same thing.】

【Good...】

The candlelight flickered.

When communicating with Yingying to this point, Aka suddenly remembered something.

【Wake up.】

Aka's brain short-circuited a bit, suddenly feeling that the two blessings provided by Mento had another deeper meaning.

"Are you afraid, Silence?" Aka turned his head and asked Ling Xin.

【Biting your brain... Could it be that the Library has a portion of authority that's with Mento?】

【The power of the curse is limited by the authority's status.】

"I've decided."

It's just that he didn't expect that the souls of the three demon sons were already fragmented, and Oogie Boogie himself was constantly weakened by hellfire, ultimately leading to the fall of the Colosseum King.

【The Library doesn't have this kind of residue; if you want to control curses, you still have to do it yourself, and even have to climb the pillar first...】
